    If you line up the first letter of the brand written on your tyre with the valve of the inner tube, it makes finding the puncture culprit much easier because you know where to look on the tyre.

  5. I put the patch on, then when I pump up the tire the patch comes off. What should I do?

  6. Thx

    i did exactly as it said in the video 3 times, and each time afterwoods the air still went down, and that was definitely the only puncture in the wheel!
    Anyone got any ideas?

  8. Shouldn’t the tire also be repaired in case of nail puncture in addition to the innertube? If yes, how do you repair the tire itself?

    You’d think somebody would have invented puncture-proof tyre for bikes, motorbikes and vehicles by now and become a millionnaire, perhaps a flexible woven metal strip incorporated in the rubber would do it.
    Alternatively perhaps a solid tyre would do the trick that needed no inflating, made out of a honeycombed rubber compound.

  10. I’ve tried 4 different kinds of adhesive I had laying around…All dried up.

    So I’m trying with superglue. Hopefully it does the same job. I know it’s strong glue but whether its flexible enough I guess we’ll see.

    Thank you 馃檪

  12. Kanthaka the white May 7, 2021 @ 1:05 am

    Washing up liquid to detect hole also useful

  13. Christian Andolini May 7, 2021 @ 1:05 am

    But its easily removable how is this good???not even sticking

  14. Lol why do they say the innertubes are expensive they are hella cheap

  15. Thanks 馃檹 put like too

  16. Oddur Sigmundsson May 7, 2021 @ 1:11 am

    I love lamp.

  17. When have a puncture, I just change the inner tube with another already 2 go, & repair the inner tube puncture at my own convenience. It makes the job easier.

    My Brother taught me this, I must of been 11 or 12. Im now 29, my son has a flat tyre and I just wanted to make sure that what I’ve been doing is correct haha.

  19. my bike was fucked by glass and then i had to walk home got embrassment it was today no one even help wtf

  20. Pomegranatepip May 7, 2021 @ 1:14 am

    Why peel off the plastic and then add chalk. Just leave the plastic on…… What am I missing?

  21. Thank you

  22. thereforeafterall May 7, 2021 @ 1:16 am

    Thx mate! I didn’t even imagine that I have to wait for the vulcanizing thing to dry first. I’m glad I watched this first! Thumbs up

  23. I just learned today that I need not consume half of the glue tube just for one puncture.

  24. Callum Pullan May 7, 2021 @ 1:19 am

    Thank you so mych

  25. How long do you let the patch bond? 5 minutes? 36 hours? Mine blew off as soon as I reattached and inflated the tyre…. Think I’ll convert to tubeless.

  26. Thomas Raven May 7, 2021 @ 1:21 am

    When on the road and I get a puncture and need to locate the hole, without the use of water in a tub, I suck my finger and slowly go round the inner tube with my finger and it helps you to feel the air escaping the puncture.

  27. Many thanks for the video – Just one question – At 3:30 , you remove the plastic cover from the cement patch – do you really need to do this ?
    I am not a bike techy so video’s like this are brilliant – many thanks.

  28. Very helpful

  35. Doof Shmoney May 7, 2021 @ 1:32 am

    I just got new kenda tires for my fixie cause my old ones had the sidewalls all messed up and all day i couldn’t figure out why it would only hold air for half an hour then deflate i but a new inner tube same problem i put it in the water patched it same problem i just realized i been putting the patch wrong with the orange side up and right after applying the glue now i fucked up the inner tube and need another one also bout a set of gatorskins tires presta valve replacements and put electrical tape over the inside of the rim over the already rim tape if this new inner tube doesnt work imma lose my mind well at least i know how to patch up an inner tube properly

  36. Why not just change the tube

  37. Good video the only thing I think you missed is to check for other bubbles, you may have more than one puncture

  38. QuadTubeChannel May 7, 2021 @ 1:34 am

    One thing that really pisses me off in the UK in certain areas is the amount of glass on the roads and pavements. It got to the point where I just gave up patching the tubes and bought some slime-filled alternatives aka ‘puncture-resitant’ tubes. Even then, I’d find glass embedded in the tyre and in a small number of cases the tyre was too badly damaged to be repaired. In my experience I’ve had the most luck with the ‘Slime’ brand of pre-filled tubes, which I find them very reliable and long-lasting. They won’t seal all flats and the slime itself won’t last forever, however I’ve been running them 15 months now and they’ve been great. I don’t have to worry about spending time to put patches on, or whether or not the glue has dried up turning the air blue xD

    Great job

  40. Thanks my wheels are punctured and I have a patch kit but I was not sure how to use it

  41. Lighton Phiri May 7, 2021 @ 1:36 am

    It finally happened—the puncture—and I found myself here. Thanks for this, really helpful!

  42. Benjamin Evans May 7, 2021 @ 1:36 am

    Could some one help me?

    If you leave the plastic over the patch,
    Is it stronger?

  43. Miriam Aldana May 7, 2021 @ 1:37 am

    what patches are those? Where can i buy them

  44. im a teacher and kids punctured my both tubes in the school in several spots now im gonna fix it

  45. Sophie鈥檚 Cycling and walking Channel May 7, 2021 @ 1:39 am

    First puncture today for years, 4 I think. Thanks for another good tutorial. My choice of tea, was lemon green tea馃嵉

  46. Using a little dish soap around on the tube rather than submerging the tube works well. The soap will bubble at the puncture site. Then, after the patch is in place, you can repeat the process to ensure the patch is holding properly.

    Thank god I saw this video I had a punctured tire here in the mountains of makiling Philippines
